Astronomers agree: Universe is nearly 14 billion years old
-
From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old - give or take 40 million years.

Wow, it doesn't look a day over 12.5 billion years old.

What's new? I have heard for the last twenty or thirty years that the universe is about that age. (well, maybe they have corrected 13.75 to 13.77 billion years, but I guess that also depends on which of the twins you are.)
The people trying to compute it using method A and the people trying to compute it using method B had improved their data to the point that the numbers + error bars for the two approaches had stopped overlapping. What's new is that this paper corrected what its authors believe to be errors in the method A approach, and got a result that is in agreement with the method B result.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies. -- Sarah Hoyt
